OMAD health benefits -

This article will cover everything you need to know before starting the OMAD diet, including how to follow the diet, possible health benefits, and risks. The OMAD diet is an extreme version of intermittent fasting.

You restrict your eating window to one hour per day while you fast go without food the remaining 23 hours of the day. For this reason, it is sometimes referred to as a to-1 IF diet. Eating for an hour within the same four-hour time frame each day is recommended.

During your one-hour eating window, you are allowed to eat whatever you want. There are no restrictions on the types of foods or beverages consumed. Additionally, there is no restriction on the number of calories you should eat.

However, eating as many calories as you would normally eat in a full day within your one-hour eating window is encouraged.

During your hour fasting window, you are not allowed to eat anything. However, some no- or very low-calorie beverages are allowed, such as water, black coffee, and unsweetened tea. There is not much research specifically on the health effects of consuming only one meal per day.

More research is needed to determine how eating only one meal a day might affect health, especially in the long term.

Nevertheless, there is some research on IF in general that may provide an understanding of the possible benefits of OMAD. Carbohydrates in food and beverages are broken down into glucose. In order to use glucose as energy, there has to be glucose or carbohydrates coming into the body.

During a hour fasting window, all the readily available glucose is used up. This leads your body to turn to a different source of energy—stored fat.

A small day study compared a to-2 intermittent fasting diet one meal per day in a two-hour time frame to a regular diet of three meals per day with snacks.

The researchers found that the single-meal-per-day group experienced increased fat breakdown for energy compared to the regular diet group. The one-meal-a-day group also saw slightly greater weight and fat loss compared to the three-meals-per-day group.

An older but longer study from looked at the effects of consuming one meal per day for two separate eight-week periods over six months compared to three meals per day control group.

At the conclusion of the study, participants eating one meal per day had significant reductions in fat mass and body composition compared to the control group.

Some research has shown that changing eating patterns through intermittent fasting may result in improved metabolism the processes that create and use energy in the body. The improved metabolism may be a result of IF inhibiting multiple pathways that promote growth and instead stimulating reactions that break down and destroy old, damaged cells, proteins, and other substances.

This, in turn, improves energy production at the cellular level, as well as overall cell metabolism. Intermittent fasting during the day has been shown to increase the amount of orexin-A, a chemical that makes you feel more alert.

After eating your meal, orexin-A levels would decrease and may help you sleep better at night. Though OMAD does not restrict the number of calories or types of food you eat, it might help with weight loss in some people.

A review of six studies on IF concluded that IF was comparable not superior to calorie-restricted diets for short-term weight loss in adults who were overweight or had obesity. A study with over 50, participants researching meal timing and frequency concluded that an to hour overnight fasting window and a five- to six-hour eating window with two meals preferably breakfast and lunch and no snacks may be beneficial for weight management.

OMAD may be difficult to maintain over time. Due to the restrictive nature of the OMAD diet, it tends to have a high dropout rate. When you are eating one time per day and fasting the rest, your body may produce more ghrelin —a hormone that stimulates hunger. A study involving people with type 2 diabetes compared eating six small meals daily to two large meals daily breakfast and lunch.

The group eating two meals per day had higher fasting ghrelin levels than the group eating six small meals daily.

If you are hungry throughout the day, you may be unable to concentrate, feel irritable, or develop a headache.

The OMAD diet is not calorie-restricted. You are allowed to eat as much as you want during your one-hour eating window. Going so long without food each day, you might be very hungry by the time your eating window comes.

This may lead you to binge-eat whatever foods are readily available and then overeat more than your body needs in a day. With such a short time frame in which to eat, you may not be able to fit in the variety of foods and nutrients your body needs each day.

It can be hard enough getting a variety of foods in each day with three meals and snacks, let alone one meal. A multivitamin and omega-3 supplement can help. The OMAD diet is not for everyone. There may be potential health risks for people with cardiovascular heart disease or diabetes.

It also might not be a good idea for people with digestive conditions , those under age 18, people with a history of eating disorders , or who are pregnant or nursing to follow the OMAD diet.

The study looked at the effects of consuming one meal per compared to three meals per day in healthy individuals. While the study showed some positive effects on health, such as decreased fat mass, it also showed some negative health effects.

In particular, significant increases in blood pressure and in total cholesterol , low-density lipoprotein LDL, considered bad cholesterol , and high-density lipoprotein HDL, considered good cholesterol levels were seen. However, further studies have shown conflicting results with respect to IF.

One study looked at blood pressure and blood pressure variability in people with newly diagnosed hypertension high blood pressure or prehypertension the stage before high blood pressure before and during IF. The study concluded that IF either significantly decreased or had no significant change in blood pressure at different times of the day.

However, the researchers saw an increase in blood pressure variability during IF, especially in people who woke early to eat before sunrise.

Higher blood pressure variability may increase the risk for coronary artery disease, stroke, and cardiovascular death. Another study in men with prediabetes the stage before type 2 diabetes found that IF improved blood pressure, oxidative stress not having enough antioxidants in the body to get rid of unstable molecules called free radicals , and insulin sensitivity when cells effectively use glucose to reduce blood sugar.

A review of studies concluded that IF may improve both blood pressure and cholesterol levels. If you are at risk for or have high blood pressure or high cholesterol, talk with a healthcare provider before starting a new diet, including IF or the OMAD diet. Eating an entire day's worth of food all within one meal in an hour can cause blood sugar glucose levels to rise significantly after eating.

Following that blood sugar spike with fasting for 23 hours can then lead blood sugar levels to drop and crash or go too low. Low blood sugar levels hypoglycemia appear to be the most severe acute immediate, short-term side effects of IF.

One study investigated IF in people with diabetes during the month of Ramadan, the ninth month of the Islamic calendar in which followers fast. Researchers identified hypoglycemia events during periods of IF, particularly in people who also used blood glucose—lowering medications, such as insulin.

An older randomized controlled trial found that people who ate one meal per day had higher morning fasting blood sugar levels, as well as greater and more sustained rises in blood glucose levels compared with people who ate three meals per day.

People who ate one meal per day also experienced a delayed insulin response during an oral glucose tolerance test. However, despite these risks, some studies show IF being beneficial in regard to blood glucose levels. A randomized controlled trial found that IF resulted in significant reductions in blood glucose.

Another study in men participating in IF during Ramadan found that IF had no significant change in fasting blood glucose levels but did improve insulin sensitivity. A review and meta-analysis of studies concluded that IF may improve blood sugar levels in people with impaired blood sugar metabolism.

Always talk with a healthcare provider before starting a new diet, especially if you are at risk for or have a chronic condition such as diabetes. OMAD one meal a day is a severe form of intermittent fasting IF where you fast for 23 hours a day and are allowed to eat whatever and however much you want during a one-hour time frame.

There is not a lot of quality research on the OMAD diet specifically. However, there is much research on the health effects of IF in general. IF may help you burn fat, be more alert, improve metabolism, and aid in weight loss or weight management.

Results are mixed on whether IF is beneficial for blood pressure or cholesterol. IF may pose a risk to people with diabetes, especially those who take insulin or other glucose-lowering medications.

People with other health conditions may be at risk when trying IF and OMAD as well, including those with digestive conditions, a history of eating disorders, or who are pregnant or nursing. National Library of Medicine.

A controlled trial of reduced meal frequency without caloric restriction in healthy, normal-weight, middle-aged adults. Proponents of this approach say that occasionally going OMAD helps them process info faster and be more decisive.

In addition to the lifestyle-related benefits listed above, OMAD can impact your health in several incredibly beneficial ways.

It may:. Intermittent fasting is one of the best ways to improve gut health by allowing your digestive system time to rest and repair itself. Also known as LPS lipopolysaccharides , endotoxin is a large molecule that accompanies gram-negative bacteria.

Your gut microbiome synthesizes endotoxin when faced with chronic stress or bacterial infection. A small amount of endotoxin production may not be harmful — but large amounts of endotoxin can transfer into the bloodstream—especially if you have leaky gut — causing problems related to inflammation and cell damage.

Temporary calorie restrictions — such as those produced by OMAD — may directly reduce endotoxin levels. These calorie-restricted CR animals had more lean mass, less fat mass, and better insulin sensitivity than their non-CR counterparts.

In the meantime, OMAD presents a great way to simulate calorie restriction while still consuming a normal amount of total calories.

This study concluded that intermittent fasting holistically improves gut health. One study of healthy adults found that eating within a daily four-hour window led to far greater fat loss than a calorie restricting diet featuring three meals a day.

It appears that OMAD activates the metabolic state called ketosis that switches the body to metabolizing fat into energy molecules called ketones. Like other types of fasting, OMAD promotes a cellular process called autophagy. Autophagy occurs when damaged cells are broken down, recycled, and used to form new cellular components.

Autophagy may also allow your liver to remove stored toxins from the body. Some studies claim that occasional dry fasts can boost mood, activate the immune system, and speed the transition into ketosis.

Dry fasting could also upregulate autophagy even further. These benefits include the prevention of cancer, diabetes, and autoimmune diseases. In addition, autophagy may slow down the degeneration that normally comes with aging.

Fasting has been used to reduce pain and inflammation for thousands of years. Lower levels of inflammation, in turn, are associated with: [ 11 ]. These benefits are associated with general fasting techniques.

The standard American diet can cause several types of hormonal imbalances. One of the most significant hormone imbalances is known as hyperinsulinemia. Chronic hyperinsulinemia can lead to more severe health problems including:.

Hyperinsulinemia triggers a negative feedback loop, meaning it makes itself worse over time — but OMAD might be able to reverse this vicious cycle. Medical professionals have been using fasting to reduce hyperinsulinemia for over years.

Some studies imply that OMAD works for weight loss almost regardless of what you choose to eat for your daily meal.

These guidelines can help;. You might want to eat fish one day, beef the next, and an omelet the day after that. Some experts believe that building some variability into your OMAD diet may provide even better results.

Keeping things diverse is also a great way to make OMAD more sustainable. While you can technically eat anything on OMAD, this way of eating works best when coupled with animal-based, keto-friendly foods that will fuel ketosis. People with higher activity levels may want to incorporate higher amounts of carbs.

It sure is. Most people find that fat simply burns off on OMAD. Water-weight should melt off, too. OMAD is somewhat unique in the sense that it can allow for weight loss without accompanying food cravings and hunger pangs—especially when eating a diet high in satiating animal fats.

Yes — just keep your coffee sugar-free in order to not break your fast. Some OMAD proponents do allow coffee with healthy keto fats like butter , cream, or MCT oil during the fasting period, as these foods are virtually free of insulin-spiking carbs.

That depends in large part on eating well-formulated nutrient-dense meals. If you have any of the following goals, OMAD could be a great fit for you:.

OMAD is a particularly simple take on intermittent fasting that offers numerous benefits to lifestyle and health.

It can boost productivity, increase focus, balance hormones, improve gut health, reduce weight, and promote cellular regeneration.
